Fluke 435-II Power Quality and Energy Analyzer

Categories

Documents

The Fluke 435 Series II Energy & Power Analyzer locates, predicts, prevents, and troubleshoots power quality problems in three-phase and single-phase power distribution systems. Fluke 435 Series II power quality analyzers feature an energy loss calculator, which identifies issues and measures the amount of energy loss in dollars. These analyzers also offer PowerWave Data Capture, which captures three-phase high-resolution voltage and current waveforms for up to five minutes along with detailed RMS voltage and current values.

Multiple parameters of the Fluke 435 Series II are measured simultaneously and displayed in formats that quickly describe overall power quality health while giving you the detailed information you need to make better maintenance decisions. Data can be quickly accessed as simple digital values, trend graphs, waveforms, phasor diagrams or analyzed and organized into a tabular format.
